Definitions
- the invention relates to an arrangement for visual and quantitative 3-D examination of samples .
- the invention relates to a Stereo microscope with a confocal scanner that parallel the visual Examination of samples as well as data acquisition with a confocal Scanner enabled.
- the basic structure of a stereo microscope is from the German Design registration 400 04 640.7 known. There are several Embodiments presented by a stereo microscope.
- the Stereomicroscope enables the visual three-dimensional observation of a Sample by the observer. If the picture is e.g. with a CCD camera recorded, the viewer only receives a two-dimensional image.
- the German patent application DE 196 32 637 discloses a method for Generation of parallactic sectional image stacks for the high-resolution Stereo microscopy.
- the method it is possible to make 3D animations of the spatial object by generating a series of slice stacks or to achieve sectional image stack pairs. This creates a stack of layplanes achieved by moving the depth of field of the microscope objective in discrete steps along the optical axis through the sample. So will won a batch of sectional images.
- the lay-up stack becomes one parallactic sectional image stack pair formed, the parallactic angle for stereoscopic vision.
- the 3-D representation of the pictures a display should, however, require considerable computing effort.
- the basic structure of a confocal scanning microscope with scanning device is from the U.S. Patent 4,863,266 known.
- the scanning microscope allows it to increase the resolution and contrast in three dimensions. Likewise can to get 3-D information from the object. Unfortunately, the device allows not a visual 3-D view of the sample to be examined.
- the invention has for its object to provide an arrangement that in addition to a visual 3-D observation of the sample, a quantitative 3-D analysis of the sample to be examined.
- the invention is also intended enable a 3-D representation of a sample with high quality and thereby the computational effort or other mathematical methods that a require considerable time to reduce.
- the objective problem is solved by an arrangement that thereby is characterized in that a confocal scanning device with the Stereomicroscope is connected to that of the confocal scanning device defined scan beam path scans a sample to be examined and records data for a 3-D image representation of the sample (6).
- An advantage of the invention is that with a stereo microscope both Visual as well as confocal scanning of the sample to be examined is possible. It is necessary to have a confocal scanning device connected to the stereomicroscope such that one of the confocal Scanning device defined scan beam path a sample to be examined scans and thereby data for a three-dimensional image representation of the Sample.
- the Stereophotography are dispensed with, the two illustrations of the object created different perspectives.
- the three-dimensional thus obtained Pictures are often of disappointing quality.
- these recordings elaborate to manufacture and require considerable consideration apparatus expenditure.
- Through the one connected to a stereo microscope confocal scanning device one can consecutively record multiple images create different levels of a sample. This data is e.g.
- the stereomicroscope 2 has a first and a second eyepiece 8 and 9, both in the first and second observation beam paths 4 and 5, respectively are arranged.
- a deflection prism 13 is used in each of the observation beam paths 4 and 5, which guides the observation beam path in the stereo microscope 2 accordingly.
- a plurality of tube lenses 14 are provided in the first and second observation beam paths 4 and 5. Downstream of the tube lenses 14 is an objective 12, which together images the first and second observation beam paths 4 and 5 onto a sample 6.
- the sample 6 can be located on an object support table 15, for example.
- the scanning device 1 defines a scanning beam path 3, which is also imaged onto the sample by the objective 12.
- FIG. 2 Another embodiment of the invention is shown in FIG. 2 . All elements of FIG. 2 that are identical to the elements of FIG. 1 are identified by the same reference numerals.
- the scanning device 1 is arranged with respect to the scanning microscope in such a way that the scanning beam path 3 can be coupled directly into one of the two observation beam paths 4 and 5.
- an optical coupling element 7 is provided in one of the observation beam paths 4 or 5, which leads the scan beam path 3 into an observation beam path.
- the scanning beam path 3 also passes through at least one of the tube lenses 14.
- the scanning beam path 3 and the illuminating beam paths 4 and 5 are imaged on the sample 6 by the objective 12.
- the optical coupling element 7 is coated in order to protect the observer from the illumination laser light of the scan beam reflected by the sample.
- confocal Scanning microscopy is used to scan a sample with a light beam.
- On confocal scanner or scanning device generally includes one Light source, a focusing optics with which the light of the light source on the a pinhole is focused, a scanning mechanism for Beam control, a detection aperture and detectors to detect the Detection and fluorescent light.
- the lens 12 is required to Imaging the scan beam onto the sample 6.
- an optical coupling element 7 is also shown (Beam splitter) required to scan the beam path 3 in the To couple observation beam path 4 or 5.
- the focus of the scan beam is generally done by tilting two mirrors in one plane within the sample 6 moves, the deflection axes usually perpendicular to each other stand so that one mirror deflects in the x and the other in the y direction.
- the mirror is tilted, for example, with the help of galvanometer actuators accomplished.
- the fluorescence from the sample or reflection light comes back through the same scanning mirror
- the invention has been made in relation to a particular embodiment the detection aperture, behind which detectors are focused, mostly Photomultiplier. Detection light that is not directly from the focus region comes from another light path and passes through the detection diaphragm not, so that one obtains point information which can be obtained by scanning the Sample leads to a three-dimensional image. Depth of field problems occur for reasons of principle not.
- the scanning device 1 is corresponding electronics (not shown) downstream, the quantitative three-dimensional imaging of the sample evaluates. There will be several levels in a row in a sample scanned, and the stacks so obtained are processed in a similar manner evaluated.
- the evaluation can e.g. even with a computer (not shown) and an appropriate computer software.
